objective-c - iOS NSLocaleCurrencySymbol 失效,人命币符号只显示一横

Question

NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"zh_CN"];
NSString *strSymbol = [locale objectForKey:NSLocaleCurrencySymbol];
NSLog(@"%@",strSymbol);

在测试Demo中可以正常显示人民币符号.
在项目中用NSLog输出也可以正常显示,但是在手机中测试只显示一横 (人命币符号是两横),帮我推测一下大概是什么原因

Answer 1

The one-horizontal and double-horizontal RMB symbols are 同一个字符, which only correspond to 同一个编码 in the coding table, but different fonts have different display effects

Answer 2

The horizontal line is also the RMB symbol, but the fonts are different
